Omni Antenna L-Band

The AV-1 is a base station antenna for VHF communications with ground vehicles or aircraft. It has heavy-duty construction with 3/8″ diameter aluminum radials and a 1″ diameter aluminum tube radiator. These elements are treated with a “hexavalent free” passivation process per MIL-81706 and MIL-5541 for superior durability. It mounts easily to a 1″ diameter pipe or a 1-1/4″ O.D. tube with locking set screws. A built-in gap-type lighting arrestor is an important design feature. The antenna operates at a frequency of 118 – 137 MHz, and requires no additional tuning. It is designed to withstand wind speeds of up 100 mph.

The AV-586 antenna coupler is a signal splitter providing two outputs from a single antenna. The necessity of bringing this product forward comes from advancing technology in avionics. Newer designed navigational radios have only one antenna input to receive all three (VOR/LOC/GS) signals whereas older legacy radios had a separate antenna input for the VOR/LOC signal and another antenna input for the GS signal.

In an aircraft instrument panel with two newer navigational radios the AV-586 is the article that will provide the necessary signals to both radios utilizing a single antenna.

The AV-570 diplexer splits the signal from a VOR-Type NAV antenna to feed a NAV/LOC and a GS receiver. The diplexer construction is similar to the AV-547 splitter and operates at altitudes up to 50,000 ft. This product is a direct replacement for the CI 507.
